RESUMO
Introduction Juvenile nasopharyngeal angiofibroma is a rare benign neoplasm in the nasopharynx. The tumor tends to be locally aggressive and is typically seen in adolescent boys. Extranasopharyngeal angiofibromas have been reported sporadically in the literature. They most commonly originate from the maxillary sinus. Objectives A 26-year-old woman was referred to our clinic with intermittent epistaxis from the right nasal passage for the previous 2 months. Maxillofacial magnetic resonance imaging showed a lobular, contoured mass originating from the right inferior turbinate and hanging in the right nasal cavity, with dense contrast enhancement denoting hypervascularity. Resumed Report Vascular feeding of the mass was seen from the right internal maxillary artery with angiography, and this branch was embolized. On the following day, the patient underwent transnasal endoscopic excision of the mass. An approximately 3-cm-diameter mass was excised by partial turbinectomy, and the posterior edge of the remaining turbinate was cauterized. Conclusion Extranasopharyngeal angiofibromas are rarely seen, and the inferior turbinate is an extremely rare location for them. This young woman is the first case reported in the English literature of angiofibroma originating from the inferior turbinate. We should consider these neoplasms can be found in female, nonadolescent patients with extranasopharyngeal localization, and we should not perform biopsy because of its massive bleeding. .
